Very much out of shape (5)
I believe the answer is:
heaps
'very much' is the definition.
(synonyms)
'of shape' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'shape' with letters rearranged gives 'HEAPS'.
'out' is the link.
(Other definitions for heaps that I've seen before include "Lots (of piles?)" , "Mounds; lots" , "A large number; untidy mounds" , "Shape (anag) - lots" , "Mounds, stacks" .)
